Methods and systems for coordinated shaping of HEV base torque

2. The vehicle operating method of claim 1, wherein the base torque reserve is an air path torque.

3. The vehicle operating method of claim 1, wherein an amount of the base torque reserve generated is increased as the position rate of change of the accelerator pedal is increased.

8. The vehicle operating method of claim 7, wherein the updated position of the accelerator pedal and the updated position rate of change of the accelerator pedal transition the driver torque request from a positive driver torque request to a negative driver torque request.

9. The vehicle operating method of claim 7, wherein the updated position of the accelerator pedal and the updated position rate of change of the accelerator pedal transition the driver torque request from a negative driver torque request to a positive driver torque request.

10. The vehicle operating method of claim 6, wherein the shaped base torque is maintained below a steady-state value, wherein the steady-state value is a predetermined limit for the shaped base torque that prevents unnecessary fuel consumption.

13. The vehicle system of claim 12, wherein the shaped base torque is further calculated based on one or more of a drive mode, a vehicle altitude, a battery state of charge (SOC), and a transmission gear.

14. The vehicle system of claim 12, wherein the shaped base torque is further calculated based on a drive mode and a base torque limit.

16. The vehicle operating method of claim 1, wherein an instantaneous torque is controlled in a non-monotonic manner when operating the vehicle in the condition.

17. The vehicle operating method of claim 16, wherein the instantaneous torque is used to control one or more of a spark timing of the engine of the vehicle and a motor of the vehicle.

18. The vehicle operating method of claim 1, wherein an instantaneous torque is increased responsive to the driver tip-in request and decreased responsive to the driver reduction in torque demand during the condition.

19. The vehicle system of claim 11, wherein the driver reduction in torque demand during the condition is still an overall positive drive torque request.
